13. USE AND MAINTENANCE OF HEATER
Once connected to water and power network, the heater is ready for use.
By turning the thermostat knob located on the front side of the protective guard set the desired water
temperature up to 75°C.
We recommend that the knob was set to position "e". Such connection is most economic;
temperature of water is about 41°C (type BTO 5) and 35°C (BTO 10), thermal losses and scale
formation will be lower than if set to higher temperature (position II is about 55 ° C, and position III
is about 75 ° C).
The electric heater operation is indicated by a control light that is on until the water in the heater heats up to the
selected temperature, or until switched off as scheduled. Due to heating, the volume of water increases, which
causes water dripping from the combination faucet pipes. You will not prevent water from dripping by strong
tightening of the handle on the combination faucet but you may damage the faucet.
If you do not intend to use the heater constantly, you need to protect the water in the heater by not discontinuing
the power totally and setting the thermostat selector to position "*". At such setting the heater is maintained at
the approximate temperature of 9°C. If you take the heater off the power supply, you have to drain the water
from it if there is a risk that the water inside freezes. Clean the outer parts of the appliance with a mild detergent
solution. Do not use thinners or other aggressive cleaning agents. Through regular service inspections you will
ensure trouble-free operation and long service life of the heater.
We recommend that the first inspection of the heater was performed by a specialist, approximately
after two yours following its putting in operation.
During the inspection the scale, that will accumulate inside the heater depending on the quality, amount and
temperature of the water consumed, will be removed as needed. During the inspection of the heating element,
the service technician will advise of the date of the next inspection, taking into consideration the found condition
of the appliance.
WARNING:
Prior to any intervention in the inside of the heating element, the appliance has to be disconnected
from power supply!
Do not attempt to repair the heater by yourselves, call the nearest authorised service centre to do
so.
